Letters .Patent No. 74,770, dated February 25, 1868.

GOAL-HOD AND SCREEN.

vTO ALLWHM IT MAY `CONCERN:

Be it known that I, AMOS PORTER, of Charlestown, Middlesex county, State ot' Massachusetts, have i invented a new and improved Combined Coal-Hed and Sitter; and I do hereby declare that the following is a full and exact description of the same,vreferencebeing had to `the dra-wings herewith annexed, with letters of reference marked thereon. In the drawings- Figure 1 is a side view of my hed-sitter arranged to bc used as a siftcr.

Figure 2 is a top view of the same.

Figure 3 is a view ofthe perforated bottom of that halt` not shown iu iig. 2.

Figure 4 is a View from the side, in perspective, of a stationary holder to hold the two pans, (latter marked in dotted lines,) the same being arrangedto bc used as a hed; and, v

In the drawings, A B, iig. 1, are two pans or troughs, with perforated oblong bottoms (seen in gs. 2 and 3) and flaring sides, which fit together at their open tops, as seen in iig. l, where the device is shown as a. sifter. The pans are held together bythe sifting-frame -C D, igs. l and 2, which consists of a4 stout piece of wire bent at the point D, and proceeding in double length horizontally toward the pans, where the lengths proceed downward diagonally, (sce Eg. 1,) and then, separating, proceed around the sides of the pan (see iig. 2) to the other ond of the same, where both lengths becoming parallel, proceed upward diagonally, and then horizontally, to thc distance seen ings. l and 2. At the horizontal portions of each end the two lengths are fastened together. The other pan has a similar arrangementof wires, hinged to the first described, at the point CX, gs.` 1 and 2, and fastened to it at the point DX, .gs.`1 and 2, by the short cylinder DX. E, figs. l and 2, is the crank by which thc device is rotated, and by this rotation the sifting of coal-dust is performed. I sometimes use a; casting ot malleable iron, or other metal, instead of wire, for the sifting-frame.

The mode in which I perfor-ate the bottoms of the troughs or pans is pcculiaras will be seen by the figs. 2 and 3, the holes being so arrangedas that no one hole in one pan cornes opposite to a hole in the other pan. This is the sifting-arrangement. As any support may he used inditferently to hold the siftingframe during sifting, no special one is described.

I sometimes use the two' pans, when placed together, as an ash-pan, and sometimes as a coal-hed. When the device is to be used as a coal-hed, the cylinder DX is slipped back, the upper wire of iig. 1 is thrown back, by means of the hinge CX, und, the pans A and E being removed, are separated, and one is placed within the other. They then present the appearance shown by the dotted lines in tig. 4, which iig. 4 isa View ofthe hodframe, or stationary frame, consistingr of an oblong frame of wire (orother material) having four legs, F F FF, and two handles, G G.

Owing to the `peculiar arrangement'ot the holes referred to above, thedust, ic., does not sift through the bottoni formed ot' the combined bottoms of the two troughs or pans, being sufficiently tight for all practical purposes.

The operation of'rny device I have described in describing its construction; and

What I claim hereinas ot' my own invent-ion, and desire tollsecure by Letters Patent, is-

1.- VI claim the combined hod or ash-pan and sitter, when it is inade of two parts so constructed as that one half tits into or upon the other half, and the bored holes of the sifting-bottoms are so arranged as not to come opposite to eachother when one pail is put into the other, thus fitting the parts to act as a hod'or ash-pan, all substantially as described.

I 'claim the rotating holder or sifting-frame to hold the two partsroi` the hodsit'ter together, in com'bination with the hod-sifter, when all are constructed and used substantially as described.

3. I claim the stationary holder or hed-frame, when constructed with hails or handles, in combination with the two containing-vessels or pans, when bored in the bottoms, all substantially as described. g

4. I claim the general construction and arrangeincnt of the whole device, when made and used substantially as described.

AMOS PORTER.
